would you be able to talk to him? my friend liked this boy who shed only spoken to once before then we started talking 2 him and now they are going out.x

Just start a conversation with him. A conversation that will actually continue. Talk about something that gives him a chance to say more then one word. Instead of being like 'Did you have a good weekend', say 'What did you do this weekend'... so it prompts him to give more then just a one word answer. Avoid asking yes/no questions because the conversation will get dull.
